Question about Vestax Pmc07pro DJ Mixer System

4 Answers

White noise in left channel on my Vestax PMC 06 pro-a DJ mixer

Its not an earth buzz kind of sound, its more like the roar of static on a TV or radio not tuned in, it can only be heard when the channel is switched to phono, i have tried switching the line/phono selector for the other channel's and it makes no difference. The noise can still be heard with nothing plugged in and listening through just headphones. Music can still be played through the channel, but the static roar is still in the background. It cannot be heard with the volume fader down. the noise is only heard in the left of the stereo output (or in the left ear of headphones), and the eq controls have no effect on it. any help would be greatly appreciated!

Replace U1 on the input board.

Use a TL 082 IC available for 2 dollars from Radio Shack.

Align the IC the same as the old one.

This IC is nect to the wires that are glued to the board and does RIAA equalization for the turntable input.

Try it with nothing plugged in to the inputs, if there is no noise. most likely its the turntable, cd player, or whatever the input is is the problem. or try plugging the mixer into a different area of the house/room. its like if you were to put your cell phone by a mixer, or speakers.

I have a crosley record player, the kind that can play CDs, iPods, tapes, and is a radio too. When I play records either no sound comes out of one side or just static. Both sides get static though. It's...


It's possible that the wires that connect the cartridge where the stylus fits are loose or broken off. With it set to the deck, have the amp on. Lift up the arm and touch the wire connections to the cartridge. You should hear a buzz on each of the channels depending on which wires you touch. You can also disconnect the wires from the cartridge and carry out the same test. On one wire it will buzz on the right, on the other on the left. The two other wires are earths and will cause only a slight buzz or nothing at all. This test proves the pre-amp inside the amp is working. If the wires are connected properly to the right connections on the cartridge, you should hear sound. If the connections are good and the sound poor or absent you need a new cartridge.

Speaker produces noice/static/buzzing sound when it is off


That means that if too much power is going to the speaker or extraneous signals are being picked up by the wiring, it can come through the speakers as static. Stopping static requires finding and eliminating that extra electricity from transmitting through your speakers.
If you're still hearing distortion, turn down the volume on your amplifier until the distortion goes away. If the volume is too low to be easily heard, the problem may be that your amplifier produces too much power for your speakers to handle or that your amp and speakers have different impedance ratings.

I have not received a diagram of my stylus wiring. none of the sites that was recommended have helped. do you know the purpose of each color of the four wires?


One is earth for the right, one is earth for the left, one is right channel and the other is left.
You don't need to know the colours to find the left and right channels. Just connect the turntable to the amp switch on. Then with your finger touch each wire one at a time. One will buzz on the left the other will buzz on the right. You might even get a slight buzz from the two earths.
The cartridge might have the left or right channels marked so you can connect them, but if it doesn't just connect the left to one side and the right to the other, then do the same with the earths. try it out, if the channels are the wrong way round change them, if the sound doesn't sound right change them again and again till it sounds right. You won't damage the amp or cartridge from doing this. Unless it's some kind of static effected cartridge!

Noise , sounds like ungrounded, all the cables are fine , the connection is grounded


so its a buzzing noise. are your turntables grounded? some dont have to be. the buzzing could be several things feedback from something around you or the mixer is buzzing cause of to much power. just mess around w stuff your not gonna break it. and what i mean about that is more wires check wires. dont preform open heart surgery on your equptment. sometimes the buzzing means the faders are going i own 3 vestax mixers and on my pmc 17a right before the faders went i had massive buzzing sound.

Hello! We have some problem whith 1 chanel, when 2


BOTH turntables and the same channel on each? If it's really really low and tinny that would probably be a failure to have/use a PHONO preamp (built-in and selectable on the Mixer).

Swap the channels coming in from the mk1200 and see if it stays with the mk1200 or with the left channel of the mixer.

There IS an outside chance you have flaky connections at the cartridge.

Power cord get really hot.


If mixer is working properly, check the rating of the adapter versus what the unit requires. Some sites indicate this requires a 12 volt adapter rated at 1.2 amps.

The right output channel on the right side of my pmc 05 pro 4 has very low output. I can hear both right and left output channels in the headphones when I have the cue selected but when I try to monitor...


I assume you swapped thee output leads as well as the inputs which you di mention, to verify you amps and cables...
The Vestax schematic I have is NOT your same model, but the companies often re-use circuitry. In the schematic I have it appears that the two channels go through two levels of NJM2068L op amps.
In these two levels there is both a master gain control. It is important to know whether the gain control varies the output level of the right, even if it is low. Also in this gain control area is a master balance pot which varies the ratio of the left and right and is CAPABLE of taking either channel to near zero output... IF you have that control check it for sure !!! The pot is a dual employing both an A taper and C taper which is a reverse of the A.
The right tool for troubleshooting this is an oscilloscope, but first an inspection looking for board cracks around the output and pot area is in order.
